[Profiling Problem]
Although perf can record the events (with call stack) of a specified pid, e.g.
using
"perf record -g iozone -s 262144 -r 64 -i 0 -i 2". But we find iozone is
interrupted
That command tells perf to *only* collect data for iozone. This command:
perf record -g -a -- iozone ....
tells perf to collect samples system wide as long as the iozone process
is alive.
